Kaolin-clay calcium carbonate pigment mixture comprising a lignosulfonate free dispersant |
| abstract |
In a process for preparing a white pigment mixture suitable for coating paper wherein a cationically bulked kaolin clay pigment is dispersed in water in the presence of an anionic dispersant and mixed with a calcium carbonate pigment, the improvement which comprises using an epichlorohydrin amine complex to bulk said kaolin, and employing as the dispersant the combination of at least 0.2% based on the dry weight of said cationically bulked kaolin of a condensed naphthalene sulfonate complex having a molecular weight of 2000 to 10,000 and a sodium polyacrylate salt having a molecular weight of 2000 to 5000, said dispersant being free from lignosulfonate. |
